Engine Mechanical problem
1986 Oldsmobile Delta 88 6 cyl 72000 miles

I just bought a 1986 Oldsmobile Delta 88 a couple of days ago. It has only 72000 miles. The check engine light came on a couple of times after driving it for awhile. It goes away automatically or if I shut off the car and restart it, it doesn't return for awhile..
Im not sure what the problem is... Also the Gas gage will go from full (show full forever) and all of a sudden drop down to a 1/4 of a tank. Please help
